It's Fun to Play the Piano ... Please Pass It On!

Have just received the complete "Service Manual" for the CLP-990/CLP990M which comprises 7 PDF's including schematics for the circuits. There are some very interesting illustrations and graphics for all of the parts in the piano as well as keyboard maintenance/regulation tips.

Here are the keys and action parts in four pages - first two images are the graphics and the next two are the names/specs of the parts.

I've owned my CLP990 for over 10 years now and have to say it still works like new and has not needed any work on it done after all these years and lots of playing. You'll definately enjoy the uniqueness of it and wonder why Yamaha abandoned clearly superior technology all those years later when they could have kept on enhancing this technology making it even better.

Good point about the CLP900 regarding its flagship status. I've not had the pleasure of playing one. But everything I've read suggests that, despite its age, it's as good or better than any of the newer Clavinovas.

As I now have a new Polaroid camera I can take a few pictures after the Clavinova CLP-990M arrives. I didn't intend to take shots of my other digitals as there are only four that I now own, in all:

1) Roland V-Piano2) Kawai CA953) CLP-990M4) Kawai EP3

I plan to have a "flagship" model from each of the major brands, i.e., Roland, Kawai, Yamaha, as the last digital (or, EP3) is just a portable stage piano with standard plastic keys and a two-sensor action, nothing special.

Also, I could never own more than three (3) flagship models due to lack of space in my small studio room. Two of the three models have upright cabinets and along with the V-Piano they do not take up as much space as a real grand piano, or, an AvantGrand, which I do not want. The V-Piano and CA95 are along one wall side-to-side, whereas the CLP-990M will be on the opposite wall with a futon bed in the middle. The smaller EP3 will be moved out into the kitchen area to make room for the CLP-990 that is going to take its place. After the CLP-990 arrives that's it, as I am not buying any other digitals. I might consider trading up on either the V-Piano or CA95 later should a better model come along, otherwise I am keeping them.

Also, will be making a recording to demonstrate the excellent "Grand Piano 1" default preset, shortly.

*Extra note:

As for the quality of the picture I took (with a Polaroid instant camera) please disregard the small white specks on the bench and piano which are not debris or paper but just specks of dust/scratches on the photo itself and scanner screen. Otherwise, the piano would have been spotless!

I thought you might want to know (along with everyone else) that I had some minor adjustments made to two keys that were sticking on my Clavinova CLP-990M (now 13 yrs. old) and both keys were freed up using a simple clamping tool which widens the hole in the wooden key where it sits upon the pivot pin in the key bed - same adjustment is used for acoustic piano keys.

Happen to have a local technician that has worked on Clavinova's over the years and knows a lot about digital piano repair. The key in getting repairs done correctly is knowing someone that has experience.

I suppose a mini-file wouldn't suffice? Like you`d use for modeling . .? Can NOBODY do anything for themselves these days?

@peterws,

The repair the technician did was not that easy when you consider he had to take quite a few things apart just to get at the key bed to do the adjustments. I wasn't going to take a chance with messing something up when the sliding keyboard cover and main control panel had to be removed before one can remove the individual keys.

If you want something done half-a**ed then do it yourself, otherwise there are real techs that know how to fix stuff the right way.

You know, PV, on a grand piano, the keybed is so easy to detach; a few large wood screws, and away it comes. But it`s so much fun to take these things apart, I think I`d have given it a go. It`s just what some fellas like to do.

You only have to look at those Nekkid pictures of Dewsters to know that. Even new stuff isn`t sacrosanct!

In your eBay listing you might want to list and describe the style of cabinet (i.e, Rosewood / Mahogany) of your piano.

The CLP-990 was available in two finishes originally, Rosewood or Mahogany, and I was very fortunate to have found a seller that owned the Mahogany which is considered to be the rarer of the two that were available. The Rosewood has a darker hue whereas Mahogany is somewhat lighter in appearance with a slight reddish tint to the grain.

I am the happy new owner of CLP-990M, in decent shape except the pedal assembly is out of the piano with only the housing and pedals left. Yamaha no longer sells the complete assembly but they do seem to carry some of the individual parts. I was wondering if you would be kind enough to send me a scan of the pedal assembly from your service repair manual so I can see what parts I need to order to make repairs.
